Boring Sunday... I did a Benchy run on a recently upgraded 850 Pro 512GB with Rapid mode enabled:-

normally sata ssd's are much cheaper because they are fairly common now. newer technologies like m.2 are relatively expensive (pci-e x4 ssd is about 2 times the price of sata ones), however it's still the best option for speed in a year or two, before we have the chance to use nvme ssd. (looking at the trend of many laptops released this year have already implemented pci-e x4 m.2 slots)

sata express. well, hopefully it will survive.

haha.. still, new techs are always the main motivations to many of us to move forward

to many, there is really no need to go for latest techs. for general use, sata ssd is more than sufficient imo (even without ram cache). they can just enjoy cheaper technologies, without the need to wait for new techs. they just start getting these much faster ssd's when their price are much affordable. (and to be frank, they miss nothing in the process). i have tested m.2 ssd with ram cache. that's why i think up to certain points of speed, we cannot see the differences already (except for benchmarking).

sata is apparently not for ssd, but it is still a mature technology for hdd. since hdd is the cheapest storage device available, i believe sata will not phase out that soon. (compared to rapidly evolving ssd techs)

yes. there are still a lot of rooms for improvement in technologies surrounding ssd. some were already discovered but yet to be implemented. then, after speed we still want much better endurance and reliability, all at the affordable price. it's a long way to go before ssd gets really matured.

it's better to grab what we can now and have fun first, rather than waiting for the next best thing. (.. for like forever)

I'm in the market looking for an SSD to replace my 160GB Intel.

I was thinking of getting a ~500GB SSD, but the 1TB Samsung 840 Evo caught my eye. It has much better $/GB than other SSDs.

Any catch behind it?

wow i totally forgot about this. thanks man running it now.

edit: the restore process took some time. it's best to run the process without anything else running, or it will run very slowly.

at first glance, everything is back to normal. both are working at good speed for now. let's see if something get slowed down after some times.

840 EVO sata:
[attachmentid=4172362]

840 EVO msata:
[attachmentid=4172361]

no you only need to run the tool once bro

those defragment tools are hdd defragmentation tool, not ssd-based. yeah it writes a lot to your ssd. the idea was to rewrite everything so that samsung 840 evo is aware of the changes and treat old files as new. samsung magician does nothing to fix the bug unfortunately.

er.. i think it's about 20 minutes for each? my drives are quite empty.

uh? don't use that if you have applied the fix. that fix is supposed to fix everything so that 840 evo will become a 'normal' ssd again.

defragmentation is not good for ssd (it's actually for hdd only), and normal ssd doesn't need it. all you need is trim, it's already built-in in w8.x (right click on the drive, select properties, then click the optimize button under 'optimize and defragment drive' area). alternatively, you can use magician's optimization feature. also, leave your machine alone for a few hours during weekends for ssd self optimizations (i.e. garbage collection, gc).

however, when the drive becomes terribly slow, (usually after a year or two, but the time frame depends on your usage also) you can do a secure erase to 'refresh' the drive back to its factory state.

yes, if your drive is filled with stuff it will take longer

by the way, here is how M2P4A from bplus looks like. (the pci-e adapter with heat sink for samsung xp941)

haha mobo's don't provide these. i need it because i have a bare m.2 ssd only. i have seen many pci-e ssd's like intel p3000 series, which are already prepackaged nicely. all you need to do is plug and play

gg actually
i think will get around november
problem is my mobo only support till sata 2
cant really get full speed of ssd yet
wait until end of year upgrade mobo then should be support full speed

haiz ...
dunno go for samsung or intel
lol confusing le lol XD

putting aside 'fake' performance, samsung still produce some of the top ssd's in terms of reliability, endurance, and speed. these days many oem manufacturers are putting samsung drives in their products (consumer and enterprise alike). there is one thing weird about intel drives, but that's just my thought. if i can gather more proofs i will share with you guys.


i stopped using my samsung 840 evo too, and am getting ready to test if there is anything wrong about the old data on them later. it needs time to validate this part.

wao now i am hype on getting 840evo 250gb or long warranty intel 530 240gb

yeah price is definitely samsung's advantage if you're talking about common sata/msata variants. however it's not just that. what surprised me was the adoption of pci-e x4 m.2 ssd's in asus g-series released recently (especially g751, g771). by the way, asus's implementations with these m.2 ssd's are by far the better one (i.e. m.2 bracket serves 2 purposes: as a placeholder, and as a heat spreader)

haha right we were all affected by the slow read bug in 840 evo. after the update that bug seemed to be gone. just now i checked the read speeds of my 840 evo and they were good. will do tests again after a few weeks.

i have no idea about asus' sata-e drive. imo sata-e will not gain popularity very soon. it is too bulky.

yeah will post an update here same here everything is good:

samsung 840 evo, 500gb sata:
[attachmentid=4199146]

samsung 840 evo, 500gb msata:
[attachmentid=4199147]

edit: as comparisons, here are the results of samsung sm841, and crucial m500.

samsung sm841, 512gb sata:
[attachmentid=4199166]

crucial m500, 960gb sata:
[attachmentid=4199168]

[attachmentid=4199169]

oh this one. yeah looks are all good. it's like msi super raid2 in their high-end laptops.

previously i waited for their pci-e adapter kit for m.2 ssd. unfortunately it took like forever so i just went for bplus :/

hopefully it's not a teaser.

yeah to me it's an enclosure with a raid card inside it. because of compact form factors, we can put msata or m.2 ssd's inside. (i think it can at least take up to 3x full-size msata) 2x 128gb should be minimum. max maybe 3x 1tb? (if 3x ports are provided. the bottleneck might be the total bandwidth supported by sata-e if it's nvme hehehe)

i think it does no harm to ssd. (it's just normal raid 0) as long as trim is supported performance should be good.

ok story time

technically, to get rid of bottlenecks by sata's  bandwidth limitation, pci-e is used to provide more bandwidth to ssd so that it can run much faster in a system. commercially, most people thought pci-e 2.0 x2 is good enough for the market. (so that they can earn more money before releasing more powerful versions, i.e. from pci-e 2.0 x2 to 2.0 x4, then 3.0 x2, finally 3.0 x4. you know the drill)

however, two companies thought otherwise.

the first one was samsung. instead of following the norm, they released xp941, a pci-e 2.0 x4 m.2 ssd to oem in year 2013 (that's the first pci-e consumer-centric ssd). with that move samsung was forcing everyone to change their game plans, including totally skipped pci-e x2 to be at least competitive. initially there were not much enthusiasm among these oem. until the second company reacted. a few months ago, asrock put an ultra m.2 slot (1x pci-e 3.0 x4) in their product lineup, the extreme series. back then, those were the only mobo that provides such a m.2 slot. on top of that, despite this premium feature, they sold them cheap. that move made asrock to suddenly become one of the best recognized mobo manufacturers almost everywhere, and their products were recommended and awarded in macam-macam best awards.

all the above happened in a year. see? these companies really can make a difference if they want to.

now the market is populated with compatible slots. (desktop mobo's, laptops) this year samsung did it again to complete the whole story. this time they announced sm951, the first consumer-centric pci-e 3.0 x4 nvme ssd. (sm953 is for enterprise) maybe we can get hold some of these beasty ssd sometimes next year

edit: this was one of the reasons why i got a lot of samsung drives. (more than 10 hehe) i am not their affiliate, or fan boy, or whatever you wanna call it. i just wanna support companies like this to make a difference in the development of better ssd's. (only ssd. the rest i am not that keen hehehe)
